Suppose you work for a pharmaceutical company that is testing a
new drug to treat ulcerative colitis. You conduct a random sample
of 30 patients on the new drug and 11 of them indicated a decrease
in symptoms since starting the drug regimen. You construct a 90%
confidence interval for this proportion to be ( 0.2224 , 0.511 ).
What is the correct interpretation of this confidence interval?
Question 6.A options:
1)

The owner of a local supermarket believes the average number of
gallons of milk the store sells per day is 184.5. In a random
sample of 23 days, the owner finds that the average number of
gallons sold was 280.9 with a standard deviation of 39.99. Using
this information, the owner calculated the confidence interval of
(257.4, 304.4) with a confidence level of 99%. Which of the
following statements is the best conclusion?
